Organization, Consolidation and Presentation of Financial Statements [Abstract]
General	GENERAL Description of Business In this report, when we refer to “the Company,” “us,” “we,” “our,” or “ours,” we are referring to Schneider National, Inc. and its subsidiaries. We are a leading transportation services organization headquartered in Green Bay, Wisconsin. We provide a broad portfolio of premier truckload, intermodal, and logistics solutions and operate one of the largest trucking fleets in North America. Our IPO of shares of Class B Common Stock was completed in early April 2017, and additional shares were sold in May 2017 under an option granted to the underwriters. In connection with the offering, we sold a total of 20,145,000 shares of common stock at $19 per share and received proceeds of $382.7 million. Expenses related to the offering totaled approximately $42.1 million, resulting in net proceeds of $340.6 million. Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with GAAP and the rules and regulations of the SEC applicable to quarterly reports on Form 10-Q. Therefore, these financial statements and footnotes do not include all disclosures required by GAAP for annual financial statements. These financial statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017. Financial results for an interim period are not necessarily indicative of the results for a full year. All intercompany transactions have been eliminated in consolidation. In the opinion of management, these statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial results for the interim periods presented. Accounting Standards Issued But Not Yet Adopted In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, which discusses the reclassification of certain tax effects from accumulated other comprehensive income. The guidance requires companies to disclose a description of their accounting policy for releasing income tax effects from accumulated other comprehensive income and whether they elect to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act, along with information about other income tax effects that are reclassified. The guidance is effective for us as of January 1, 2019 with early adoption permitted. We plan to early adopt this guidance during the fourth quarter of 2018 and expect the reclassification of stranded income tax effects to have an immaterial impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , which is codified as ASC 842. Subsequent ASUs have clarified and modified this guidance. This standard requires lessees to recognize assets and liabilities in the consolidated balance sheets for leases with lease terms of more than 12 months. Consistent with current accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current accounting principles, which require only capital leases to be recognized in the consolidated balance sheets, the new ASU will require both types of leases to be recognized in the consolidated balance sheets. In transition, lessees and lessors can elect to recognize and measure leases at the date of adoption or at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for us as of January 1, 2019 with early adoption permitted. We have formed a cross-functional implementation team that has both identified the population of the company's lease contracts affected by the new standard and selected a system to help accommodate the new leasing standard. We have not yet completed our assessment of the impact of the new guidance on our consolidated financial statements; however, we do expect an increase in our assets and liabilities from the recognition of operating leases on the consolidated balance sheets. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which requires companies to use a forward-looking, expected loss model to estimate credit losses on various types of financial assets and net investments in leases. It also requires additional disclosure related to credit quality of trade and other receivables, including information related to management’s estimate of credit allowances. This guidance is effective for us as of January 1, 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements.

Revenue from Contract with Customer [Abstract]
Revenue from Contract with Customer [Text Block]	REVENUE RECOGNITION We implemented ASU 2014-09, Revenue from Contracts with Customers, which is codified as ASC 606 as of January 1, 2018 . We used the modified retrospective approach for adoption, which required us to record the cumulative effect of the transition through retained earnings as of January 1, 2018. Retained earnings increased by $7.3 million upon adoption. The adjustment related only to contracts that were not completed as of January 1, 2018. The following table shows the amount by which financial statement lines were affected by the adoption of the new standard. The changes relate to the recognition of transportation revenue over time rather than at delivery, as explained below under the Transportation heading.

As defined by the new standard, a "contract" can range from an individual order to a multi-year agreement with a customer, depending on the specific arrangement. The majority of our revenues are related to transportation and have similar characteristics. The following table breaks down our revenues by type of service, and each type of service is further described below. Three Months Ended June 30, Six Months Ended June 30, Disaggregated Revenues (in millions) 2018 2017 2018 2017 Transportation $ 1,138.0 $ 979.8 $ 2,187.9 $ 1,915.3 Logistics management 53.9 52.5 106.0 104.8 Other 44.4 42.9 81.4 61.5 Total operating revenues $ 1,236.3 $ 1,075.2 $ 2,375.3 $ 2,081.6 Transportation Transportation revenues relate to the Truckload and Intermodal reportable segments, as well as to our Brokerage business, which is included in the Logistics reportable segment. In the Transportation portfolio, our service obligation to customers is satisfied over time. We do not believe there is a significant impact on the nature, amount, timing, and uncertainty of revenue or cash flows based on the mode of transportation. The economic factors that impact our transportation revenue are generally consistent across these modes given the relatively short term nature of each contract. For the majority of our transportation business, the "contract with a customer" is identified as an individual order under a negotiated agreement. Some consideration is variable in that a final transaction price is uncertain and is susceptible to factors outside of Schneider's influence, such as the weather or the accumulation of accessorial charges. Pricing information is supplied by the rate schedules that accompany negotiated contracts. Transportation orders are short-term in nature and generally have terms of significantly less than one year. They do not include significant financing components. A small portion of revenues in our transportation business relate to fixed payments in our Truckload segment. These payments are due regardless of volumes, and in these arrangements, the master agreement rather than the individual order may be considered the "contract." See the Remaining Performance Obligations table below for more information on fixed payments. Prior to the adoption of ASC 606, we recognized revenue from transportation services when we completed our obligation to the customer, upon delivery. In accordance with the new standard, we now recognize revenue over the period transportation services are provided to the customer, including service performed as of the end of the reporting period for loads currently in transit, in order to recognize the value that is transferred to a customer over the course of the transportation service. We determine revenue in transit using the input method, under which revenue is recognized based on time lapsed from the departure date (start of transportation services) to the arrival date (completion of transportation services). Measurement of revenue in transit requires the application of significant judgment. We calculate the estimated percentage of an order's transit time that is complete at period end, and we apply that percentage of completion to the order's estimated revenue. Revenue recognized in the period ended June 30, 2018 includes amounts related to orders that were partially completed (in transit) in prior periods. In certain transportation arrangements, an unrelated party contributes a specified service to our customer. For example, we contract with third-party carriers to perform transportation services on behalf of our customers in our Brokerage business, and we use third-party rail carriers in our Intermodal segment. In situations that include the contributions of third parties, we act as principal in the arrangement, and, accordingly, we recognize gross revenues from these transactions. Logistics Management Logistics Management revenues relate to our Supply Chain Management and Import/Export Services operating segments, both of which are included in our Logistics reportable segment. Within this portfolio, the key service we provide to the customer is management of freight shipping and/or storage. The "contracts" in our Logistics Management portfolio are the negotiated agreements, which contain both fixed and variable components. The variability of revenues is driven by volumes and transactions, which are known as of an invoice date. See the Remaining Performance Obligations table below for additional information. Supply Chain Management and Import/Export Services contracts typically have terms that extend beyond one year, and they do not include financing components. Prior to the adoption of ASC 606, we recognized revenue under these contracts over time, based on pricing terms within the arrangements. Our recognition model will remain the same under the new standard, as we have elected to use the right to invoice practical expedient, which reflects the fact that a customer obtains the benefit associated with logistics services as they are provided (output method). In our Supply Chain Management business, we subcontract third parties to perform a portion of the services. We are responsible for ensuring the services are performed and that they are acceptable to the customer, and we are therefore considered to be the principal in these arrangements. Other Other revenues relate to activities that are out of scope for purposes of ASC 606, including our leasing and captive insurance businesses. Quantitative Disclosure The following table provides information related to the transactions and expected timing of revenue recognition related to performance obligations that are fixed in nature and relate to contracts with terms greater than one year. Remaining Performance Obligations (in millions) June 30, 2018 Expected to be recognized within one year Transportation $ 12.1 Logistics Management 10.0 Expected to be recognized after one year Transportation 1.0 Logistics Management 4.0 Total $ 27.1 This disclosure does not include revenue related to performance obligations that are part of a contract whose original expected duration is one year or less. In addition, this disclosure does not include expected consideration related to performance obligations for which the Company elects to recognize revenue in the amount it has a right to invoice (e.g., usage-based pricing terms). The following table provides information related to contract balances associated with our contracts with customers as of the dates shown. Contract Balances ( in millions ) June 30, 2018 January 1, 2018 Other current assets - contract assets $ 27.8 $ 22.2 Other current liabilities - contract liabilities $ 1.1 $ — We generally receive payment within 40 days of completion of performance obligations. Contract assets in the table above relate to revenue in transit at the end of the reporting period. Contract liabilities relate to amounts that customers paid in advance of the associated service. For certain of our contracts, we incur upfront costs to fulfill the master agreement, including driver recruiting and equipment relocation, that are capitalized and amortized over the master contract term, which has been deemed to be the period of benefit. These costs usually relate to dedicated transportation arrangements. The following table presents the amounts capitalized for contract fulfillment costs as of the dates shown. (in millions) June 30, 2018 December 31, 2017 Capitalized contract fulfillment costs $ 4.5 $ 3.7 Amortization of capitalized contract fulfillment costs was as shown: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2018 2017 2018 2017 Amortization of contract fulfillment costs $ 0.8 $ 0.5 $ 1.4 $ 1.1 Practical Expedients We elected to use the following practical expedients that are available under ASC 606: (i) not to adjust the promised amount of consideration for the effects of a significant financing component when we expect, at contract inception, that the period between our transfer of a promised service to a customer and when the customer pays for that service will be one year or less; (ii) to apply the new revenue standard to a portfolio of contracts (or performance obligations) with similar characteristics, as we reasonably expect that the effects on the financial statements of applying this guidance to the portfolio would not differ materially from applying this guidance to the individual contracts (or performance obligations) within that portfolio; and (iii) to recognize revenue in the Logistics Management portfolio in the amount of consideration to which we have a right to invoice, that corresponds directly with the value to the customer of the service completed to date.

Fair Value Disclosures [Abstract]
Fair Value	FAIR VALUE Fair value focuses on the estimated price that would be received to sell an asset or paid to transfer a liability, which is referred to as the exit price. Inputs to valuation techniques used to measure fair value fall into three broad levels (Levels 1, 2, and 3) as follows: Level 1 —Observable inputs that reflect quoted prices for identical assets or liabilities in active markets that we have the ability to access at the measurement date. Level 2 —Observable inputs, other than quoted prices included in Level 1, for the asset or liability or prices for similar assets and liabilities. Level 3 —Unobservable inputs reflecting the reporting entity’s estimates of the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk). All marketable securities were valued based on quoted prices for similar assets in active markets or quoted prices for identical or similar assets in markets that are not active (Level 2 in the fair value hierarchy). We measure our marketable securities on a recurring, monthly basis. See Note 4 , Investments , for information on the fair value of our marketable securities. In connection with the June 1, 2016 acquisition of WSL, a contingent payment arrangement based on the achievement of specified earnings targets is in place for three consecutive 12-month periods after the closing, with the aggregate payment total not to exceed $40.0 million. No payments have been made through June 30, 2018 . The fair value of the contingent consideration at June 30, 2018 and December 31, 2017 was zero . The valuation was based on Level 3 inputs. Our investment in Platform Science, Inc. discussed in Note 4 , Investments , was valued based on Level 3 inputs. There were no transfers between levels for the periods discussed. Fair Value of Other Financial Instruments The recorded value of cash, trade accounts receivable, and trade accounts payable approximates fair value. The table below presents the carrying value of our debt portfolio along with the fair value of a fixed-rate debt portfolio with similar terms and maturities, which is based on borrowing rates available to us in the applicable year. This valuation used Level 2 inputs. June 30, 2018 December 31, 2017 (in millions) Carrying Value Fair Value Carrying Value Fair Value Debt portfolio $ 416.6 $ 407.0 $ 429.8 $ 432.4

Goodwill and Other Intangible Assets	GOODWILL AND OTHER INTANGIBLE ASSETS Goodwill represents the excess of the purchase price of our acquisitions over the fair value of the identifiable net assets acquired. Changes in the carrying amount of goodwill were as follows: (in millions) Truckload Logistics Other Total Balance at December 31, 2017 $ 138.2 $ 14.2 $ 12.4 $ 164.8 Foreign currency translation — — (0.2 ) (0.2 ) Balance at June 30, 2018 $ 138.2 $ 14.2 $ 12.2 $ 164.6 At June 30, 2018 and December 31, 2017 , we had accumulated goodwill impairment charges of $6.0 million . Prior to the second quarter of 2018, all of the goodwill within the Truckload reportable segment was attributed to the Specialty Dedicated reporting unit. During the quarter ended June 30, 2018 , we reorganized the structure of the operating segments within the Truckload reportable segment to include FTFM as a separate operating segment and integrated the remaining Specialty Dedicated activities into the VTL operating segment. Each Truckload operating segment was determined to be its own reporting unit due to the level at which financial information is available and management's review of that information. As a result of the reorganization, goodwill attributable to the Specialty Dedicated reporting unit was reallocated to the VTL and FTFM reporting units on a relative fair value basis. After the reallocation of goodwill, an impairment test was performed for these reporting units, and it was determined that goodwill was not impaired as each reporting unit had an estimated fair value in excess of its respective carrying amount. The identifiable intangible assets other than goodwill listed below are included in other noncurrent assets on the consolidated balance sheets.

Income Tax Disclosure [Abstract]
Income Taxes	INCOME TAXES Our effective income tax rate was 25.5% and 37.7% for the three months ended June 30, 2018 and 2017 , respectively, and 25.8% and 38.6% for the six months ended June 30, 2018 and 2017 , respectively. The decrease in the rates was due to the enactment of the Tax Cuts and Jobs Act in December 2017. In determining the quarterly provision for income taxes, we use an estimated annual effective tax rate, adjusted for discrete items. This rate is based on our expected annual income, statutory tax rates, and best estimate of nontaxable and nondeductible items of income and expense. In accordance with SEC Staff Accounting Bulletin No. 118, the amounts recorded in the fourth quarter of 2017 related to the Tax Cuts and Jobs Act represent reasonable estimates based on our analysis to date and are considered to be provisional and subject to revision during 2018. Provisional amounts were recorded for the remeasurement of our 2017 net deferred tax liabilities and ancillary state tax effects. These amounts are considered to be provisional as we continue to assess available tax methods and elections and refine our computations. In addition, further regulatory guidance related to the Tax Cuts and Jobs Act is expected to be issued in 2018 which may result in changes to our current estimates. Any revisions to the estimated impacts of the Tax Cuts and Jobs Act will be recorded quarterly until the computations are complete, which is expected to be no later than the fourth quarter of 2018. No changes were made to the estimated impacts in the second quarter of 2018.

These awards consist of the following: restricted shares, restricted stock units ("RSUs"), performance-based restricted shares ("Performance Shares"), performance-based restricted stock units ("PSUs"), and non-qualified stock options. The following table summarizes the components of our share-based compensation program expense: Three Months Ended June 30, Six Months Ended June 30, (in millions) 2018 2017 2018 2017 Restricted Shares and RSUs 0.9 0.6 1.6 0.6 Pre-IPO Restricted Shares 0.2 0.4 0.6 1.1 Performance Shares and PSUs 0.6 0.7 1.2 0.7 Nonqualified Stock Options 0.4 0.2 0.8 0.2 Share-based compensation expense 2.1 1.9 4.2 2.6 Related tax benefit 0.5 0.7 1.1 1.0 As of June 30, 2018 , we had $15.4 million of pre-tax unrecognized compensation cost related to outstanding share-based compensation awards that is expected to be recognized over a weighted-average period of 2.8 years .

Dividend equivalents equal to dividends paid on our common shares during the vesting period are tracked and accumulated for each restricted share and RSU. The dividend equivalents are forfeitable and are distributed to participants in cash consistent with the date the awards vest. A small portion of the restricted shares relate to a one-time 2018 grant, which vests 50% after a five -year period, with the remaining 50% vesting after a six -year period after the grant date, subject to continued employment through the vesting date.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES In the ordinary course of conducting our business we become involved in certain legal matters and investigations on a number of matters, including liability claims, taxes other than income taxes, contract disputes, employment, and other litigation matters. We accrue for anticipated costs to defend and resolve matters that are probable and estimable. We believe the outcomes of these matters will not have a material impact on our business or our financial statements. At June 30, 2018 , our firm commitments to purchase transportation equipment totaled approximately $213.5 million. WSL Acquisition The purchase and sale agreement related to our June 2016 acquisition of WSL included guaranteed payments of $20.0 million to the former owners of WSL on each of the first three anniversary dates of the closing. The liability recorded was discounted between one percent and three percent , based on credit-adjusted discount rates. The initial payment in the amount of $19.7 million, including calculated interest based on the discounted amount recorded, was made in June 2017 and reflected an adjustment for a working capital true-up. The second payment in the amount of $20.0 million was made in June 2018. The present value of the remaining payment was $18.7 million at June 30, 2018 , which is recorded in other current liabilities on the consolidated balance sheet. The representative of the former owners of WSL has claimed that we have not fulfilled certain obligations under the purchase and sale agreement relating to the post-closing operations of the business, amongst other matters, and that, as a result, the former owners are entitled to an accelerated payment of the contingent amount described in Note 3 , Fair Value , without regard to whether the specified earnings targets are met. We believe this claim is meritless and have filed an action in the Delaware Court of Chancery seeking a declaratory judgment that we have complied with our obligations under the agreement and that no accelerated payment is owed.

Segment Reporting [Abstract]
Segment Reporting	SEGMENT REPORTING We have three reportable segments – Truckload, Intermodal, and Logistics – which are based primarily on the services each segment provides. As of December 31, 2017 our operating segments within the Truckload reportable segment were VTL, Specialty Dedicated, and Bulk. During the second quarter of 2018, we reorganized the structure of the Truckload reportable segment, separating FTFM into its own operating segment and moving the remaining business that was previously under the Specialty Dedicated operating segment into the VTL operating segment. The Truckload reportable segment now consists of three operating segments (VTL, FTFM, and Bulk) that are aggregated because they have similar economic characteristics and meet the other aggregation criteria described in the accounting guidance for segment reporting. The chief operating decision maker reviews revenues for each operating segment without the inclusion of fuel surcharge revenues. For segment purposes, any fuel surcharge revenues earned are recorded as a reduction of the segment’s fuel expenses. For all operating segments except FTFM, revenue is recognized upon delivery, and in-transit revenue is not reflected in segment results. Income from operations at a segment level reflects the measures presented to the chief operating decision maker for each segment. Separate balance sheets are not prepared by segment and, as a result, assets are not separately identifiable by segment. All transactions between reporting segments are eliminated in consolidation. The following tables summarize our segment information. Intersegment revenues were immaterial for all segments, with the exception of Other, which included revenues from insurance premiums charged to other segments for workers’ compensation, auto, and other types of insurance. Intersegment revenues included in Other revenues below were $20.7 million and $20.5 million for the three months ended June 30, 2018 and 2017 , respectively, and $41.4 million and $37.4 million for the six months ended June 30, 2018 and 2017 , respectively.

Description of Business	Description of Business In this report, when we refer to “the Company,” “us,” “we,” “our,” or “ours,” we are referring to Schneider National, Inc. and its subsidiaries. We are a leading transportation services organization headquartered in Green Bay, Wisconsin. We provide a broad portfolio of premier truckload, intermodal, and logistics solutions and operate one of the largest trucking fleets in North America.
Basis of Presentation	Basis of Presentation The accompanying unaudited interim Consolidated Financial Statements have been prepared in accordance with GAAP and the rules and regulations of the SEC applicable to quarterly reports on Form 10-Q. Therefore, these financial statements and footnotes do not include all disclosures required by GAAP for annual financial statements. These financial statements should be read in conjunction with the Consolidated Financial Statements and related notes included in our Annual Report on Form 10-K for the year ended December 31, 2017. Financial results for an interim period are not necessarily indicative of the results for a full year. All intercompany transactions have been eliminated in consolidation. In the opinion of management, these statements reflect all adjustments (consisting only of normal recurring adjustments) necessary for the fair presentation of our financial results for the interim periods presented.
Accounting Standards Issued But Not Yet Adopted	Accounting Standards Issued But Not Yet Adopted In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income, which discusses the reclassification of certain tax effects from accumulated other comprehensive income. The guidance requires companies to disclose a description of their accounting policy for releasing income tax effects from accumulated other comprehensive income and whether they elect to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act, along with information about other income tax effects that are reclassified. The guidance is effective for us as of January 1, 2019 with early adoption permitted. We plan to early adopt this guidance during the fourth quarter of 2018 and expect the reclassification of stranded income tax effects to have an immaterial impact on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases , which is codified as ASC 842. Subsequent ASUs have clarified and modified this guidance. This standard requires lessees to recognize assets and liabilities in the consolidated balance sheets for leases with lease terms of more than 12 months. Consistent with current accounting principles, the recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike current accounting principles, which require only capital leases to be recognized in the consolidated balance sheets, the new ASU will require both types of leases to be recognized in the consolidated balance sheets. In transition, lessees and lessors can elect to recognize and measure leases at the date of adoption or at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that companies may elect to apply. These practical expedients relate to the identification and classification of leases that commenced before the effective date, initial direct costs for leases that commenced before the effective date, and the ability to use hindsight in evaluating lessee options to extend or terminate a lease or to purchase the underlying asset. The transition guidance also provides specific guidance for sale and leaseback transactions, build-to-suit leases, leveraged leases, and amounts previously recognized in accordance with the business combinations guidance for leases. The new standard is effective for us as of January 1, 2019 with early adoption permitted. We have formed a cross-functional implementation team that has both identified the population of the company's lease contracts affected by the new standard and selected a system to help accommodate the new leasing standard. We have not yet completed our assessment of the impact of the new guidance on our consolidated financial statements; however, we do expect an increase in our assets and liabilities from the recognition of operating leases on the consolidated balance sheets. In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments , which requires companies to use a forward-looking, expected loss model to estimate credit losses on various types of financial assets and net investments in leases. It also requires additional disclosure related to credit quality of trade and other receivables, including information related to management’s estimate of credit allowances. This guidance is effective for us as of January 1, 2020. We currently cannot reasonably estimate the impact that the adoption of this ASU will have on our consolidated financial statements.
